If the answer to either 3 or 4 is yes, please explain. Baucus' office referred Politico to a 2007 Wall Street Journal article, which indicates that the senator underpaid his Washington, D.C., property taxes between 2003 to 2005, due to a computer error made by city tax collectors. When the error was discovered, the article says, Mr. Baucus was given 30 days to pay $5,625.72 in back taxes. The senator paid a few weeks after the deadline, accruing an additional $538.86 in penalties and interest.

In addition, according to the article, in Helena, Mont., Mr. Baucus paid a small penalty in 2002 due to a misunderstanding about who was supposed to remit the first property-tax payment on a home he purchased from his brother. The $1,650 bill was paid a few weeks late, and the senator was charged $60.36 in penalties and interest, which the brothers split.

Regarding the question of back taxes, in 2008, as Mayor of Anchorage, I was issued a municipal vehicle as had been the practice for years by previous mayors and in cities across the country. Then the IRS issued a new ruling that use of this car was taxable, so I paid the back taxes owed on the “benefit” for the years I utilized the vehicle. I then got rid of the city vehicle and bought my own car to use for city business.
